TYPE-WRITING MACHINE.

Specication of Letters Patent.

Patented Feb. 8, 1910.

To all whom 'it may concern:

Be it known that I, ANDREW W'. STEIGER, citizen of the United States, and resident of Bridgeport, in the.v county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in TypelVi-iting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulatlng mechanism for such machines. a

The principal object of my invention 1s to produce a combined denominational and column selectingtabulator that can be used either for the ordinary purposes of a denolninational tabulator or for the ordinary purposes of a column selector or for both purposes at once, that is to say, to cause the carriage to move at a single operationv to a selected denominational position in any selected one of a plurality of columns.

Another object is to provide such a tabulator so constructed that it can be set to act either as an ordinary denominational tablilator arranged to arrest the carriage at any denominational position in the first column that reaches the printing position or-that can be set so as to skip any desired number of columns and to use succeeding columns only, this setting remaining fixed until the operator changes it.

To the above and other ends which will appear in the course of the description, my invention consists in certain features of construction and combinations and arrangements of parts all of which will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side 'elevation of as much of a typewriting machine as is necessary to' illustrate the. application of my invention thereto,

some of the parts of said typewriting machine being shown conventionally and others omitted. Fig. 2 is a rear elevation of the same. F ig. 3 is a to plan view of part of the base of the typewriter and -of that part of the tabulating mechanismi that is situated below the top plate, the upper part of the typewriter and tabulator being removed or sectioned away. Figl is an isometric view of the denominational stops, a fragment of the carriage. feed rack and associated devices, parts of the typewriter and tabulating mechanism being omitted and parts broken away. Fig. 5 is a side view of the hand lever that controls the selection of columns. Fig. 6 is a diagrammatic View illustrating the operation of the action of the column selecting devices on the denominational stops.

My invention is applicableY or adaptable to typewriting machines generally and the drawings show only a conventional representation of the frame-work and carriage of a typewriter in which the printing instrumentalities are stationary and in Which a roller platen is mounted on the carriage and carries the paper.

The main-frame of the machine is shown as comprising a. base 1, corner posts 2 and a top plate 3. Stationary grooved rails 4 are supported by the top plate and a carriage 5 has a rectangular frame, the front and rear bars of which are formed with grooves Which coperate with grooves in the rails 4 to form race-Ways, in which run antifriction balls or rollers 6. -The carriage is drawn across the machine by a spring drum 7 connected thereto in any usual or suitable manner and it is controlled in its step-bystep movements by an escapement mechanism of any suitable sort which is here shown as including an escapement wheel 8 mounted on the rear end of a shaft journaled in a bracket 10 secured to the top plate 3. Said yshaft has on its forward end a pinion 11 that meshes with a feed rack 12 which is' carried by arms 13 ivoted at 14 to the carriage 5 and normaly held down by springs 15. This rack can be raised out of engagement With the inion 11 in order to release the carriage rom its escapement mechanism. A platen 16 is shown mounted in the carriage 5.. The paper feed devices, printing mechanism, etc. are not shown but they may be of any usual or suitable sort.

The tabulator comprises a column stop bar 17 which is here shown as of the usual square cross section and formed in its forward and rear faces with the usual notches spaced a letter space distance apart. The bar 17 is mounted on arms 18 extending rearward from the carriage 5, said bar being secured to the arms 18 by means of screws 19 and said arms being secured to the carriage by means of screws 20.

I have shown four column stops 21, 22, 23 and 24, each of the ordinary bifurcated construction, adapted to be fitted over the stop bar 17 in the usual way except that the` All of these levers are pivoted at their angles on a cross rod 28 which is movably mounted in the machine as will appear more fully hereinafter. The actuating devices for the denominational stops include a series of links-3()7 and each of the lever arms 27 has one of these links pivoted thereto at 31 at the lower end of said lever arm. The links 30 extend downward at an inclination toward the front of the machine. their lower ends being pivoted at 32 to 'a series of levers 33 which are pivoted on a cross rod or shaft 34. Each of the levers 33 has a downwardly extending arm to which at 35 is pivoted the rear end of a link 36 which at its forward end is pivotcd at 3T to the depending arm of an angular key lever 38 having a key 40 mounted on the end of its forwardly and upwardly directed arm. As shown in Fig. 3 the links 36 flare outward toward the front of the machine so as to space the keys 4() a suitable distance apart and said keys are arranged in a row at. the back-of the keyboard of the machine; that is to say, in a row just back of the rear row of printing keys. All of the levers 38 are pivoted on a cross rod 3f) supported at its ends in the base 1 of the main frame. The construction is such that if any of the keys 40 be depressed the corresponding link 36 will operate the corresponding lever 33, which in turn through the link 30 will rock the stop lever 26, 27 and move the denominational stop arm 26 of said lever forward into the path of one of the column stops.

The support for the denominational stops and the devices immediately associated therewith, can be best understood by reference to Figs. l and 4. A bracket- -or frame 41 is mounted on the rear part of the top plate 3 by means of screws 42 passing through ears 43 bent off from said frame. This frame comprises'two uprights, one at either side of the system of denominational stops, and a cross bar connecting said uprights at the rear of said stops. Each of the upright'endsvof the frame 41 is formed with a forwardly projecting arm 44 and in said arms a rock shaft 45 is pivotally mounted. Two arms 46 are rigidly mounted on said rock shaft by means of set screws 47 threaded through the hubs of said farms and engaging said rock shaft. These arms are inside of the end pieces of the frame 41 and they extend at au inclination upward and toward the rear and they have the pivot rod 2S of the denominational stop levers rigidly mounted outheir rear ends. The-construction is such that this pivot rod can be moved in an arc of a circle by turning the rock shaft 45. Said rock shaft is controlled by an arm 48 rigidly mounted thereon and extending therefrom downward at an inclination toward the rear of the Inachine. Pivoted at 49 to the lower end of the arm 48 is a link 50, the lowerend of which is pivoted to ap arm 51 extending toward the rear of the machine from the shaft 34 on which the levers 33 are pivoted. The arm 51 is rigidly mounted on the shaft 34 in the midst of the system of levers 33, as shown in Fig. 3. This shaft is mounted or pivoted in arms 52 of a sheet -metal frame which comprises a yoke part 53 that lies on the back shelf 54 which constitutes a part of the base 1 of the main frame, said yoke being secured to the shelf by screws 55. The arms 52 extend forward and curve downward so as to bring the shaft 34 in front of the front edge of the shelf 54 and at a lower level than said shelf. The left-hand end of the shaft 34 has a collar 56 mounted thereon outside of the arm 52 to prevent. endwise 'inotion of said shaft. At its right-liand end the shaft 34 extends through the right-hand side plate of the base 1 of the main frame in which side plate said shaft is journaled. On the outside of said side plate said shaft has an upwardly extending arm 57 mounted thereon and said arm is connected by a hori zontal link 58 with the downwardly extending arm 59 of a bell crank having a forwardly extending arm G0, the front end of which is formed into a handle 61. The lever 59, 6() is pivoted on aI screw. 62 threaded int-o a block 63 forming part of or secured to the right-hand front post 2 of the main frame. The construction is such that if the handle 61 be moved downward the pivot rod 2S will be moved downward in an arc with the shaft. 45 as a center.

In order to retain the handle 61 in any one of its'several positions, a block G4 is secured to the post 2 and this block has a .se ries of notches 65 formed in its front face. Said notches are'engaged by a beveled detent 66 mounted on the handle 61. This detent may be of any suitable construction, but as here shown it consists of a headed pin or bolt, the head of which is beveled as shown in Fig. 1 and the stem of which passes through 'an elongated slot A67 (Fig. 5) formed in thehandle. -The right-hand end of said stem is threaded to receive a nut 68 which retains the detent in position on the handle. Saidvdetent is drawn toward the rear of the machine by means of a spring connected at one end to the detent and at the other end to a screw 72 threaded into the handle or into the lever arm 60. The construction is such that the detent will hold the handle in anyone of its several positions but said handle can be forced to any other of said positions, the detent snapping in and out of the notches 65. Four such notches are shown in the present instance to correspbnd in number to the four column stops.

In order to release the carriage when any denominational stop is operated, a frame is provided, said frame being mounted on the rock shaft 45 (Fig.4). This frame comprises an arm `73 pivoted on the left-hand end of the shaft 45 outside of the frame 41, and said arm is connected by a cross bar 74 with another arm 75 pivoted on the other end of said shaft 45, the cross bar 74 lying in front of the denominational stops and serving as a universal bar operable by any of said stops. The universal bar frame comprises also a forwardly extending arm 76 that is connected by a short link 77 with the rear arm of a lever 78 of the first order,

the forward arm of which lies just beneath4 the rack bar 12. The lever 78 is pivoted on a screw 80 threaded into a bracket 81 which is secured to the top plate 3 by means of a screw. The construction is'su'ch that when any denominational stop is operated the lever 78 is rocked about its pivot 80 and raises the rack bar 12 out of engagement with the pinion 11, thus releasing the carriage and allowing it to run free until'it is arrested by the stops. The release mechanism is restored to normal position by means of a spring 82 which as here shown is connected at one end to a post 83 on the arm 73 and at the other end to a post 84 on the frame 41.

In order to limit the forward motion of the denominational stops when'they are operated by the keys 40, any suitable means may be provided. As here shown, a stop bar 85 is mounted in the arms 52 above the levers 33 in position to prevent said levers from moving too far.

The operation of my tabulating mechanism consists in setting the handle 61 to the desired position and then operating the denominational keys 40 in the ordinary way. The parts are shown in Fig. 1 set so that any operated denominational stop will arrest the first column stop that reaches it. With the parts in this position the tabulator is setto operate as any ordinary denominational tabulator. In caseit is not desired to do denominational work, some particular one of the denominational keys can be used as, for example, the one of lowest order, which in denominational work usually corresponds to the decimal point. IVhen the handle 61 is moved from the, position shown in Fig. 1 into the other .three notches 65', the denominational stops operate in the manner illustrated diagrammatically in Fig. 6. In this figure the column stop bar 17 is shown and the series ot' column stops 21, 22, 23 and 24. The other parts are diagrammatically represented and are designated in this figure by the same reference numerals as in the other figures of the drawings with the exponents a, b, c or d, according as the respective positions shown correspond to the positions of the handle 61 in Fig. 1 or to the position of said handle when the detent 66 is in the second, third or fourth notch 65 as the case may be. The position of any one of the denominational stops vshown in Fig. 1 is indicated at 26a. The

corresponding position of the pivot rod 28 is shown at 28a; that of the pivot 31 at 31 and that of the pivot 49 at 49a. The positions of the corresponding parts when the detent 66 is in the second notch 65 are represented by the same numerals but -with the exponent b and so on. It will be seen that when the handle 61 is moved, each of the stop levers 26, 27 has the motion of a floating lever, the point 28 turning about the rock shaft 45 as a center and the point 31 turning about the pivot 32 as a center. The points 28a, 28", 28c and 28d are therefore in the arc of a circle having the shaft 45 for its center and the points 31a, 31h, 31e-and 31d are in the arc of a circle having the point 32 as a center. It will be seen that the effect of this on the operative'end of the sto arm 26 is to move said end downward an a little toward the front of the machine. If, when the parts are in the iirst of these positions, a denominational key be operated, the point31SL moves to 31A and the point 26a moves to 26A' where it arrests the first column stop 21. When the parts are in the second of said positions and a. denominational key is operated, the point 3lb moves to 31B and the point 261 moves to 26 Where it is in position to arrest the second column stop 22 but where the {i1-st column stop 21 Will pass over it. In the third position an operated denominational stop will `arrest the third column stop 23, allowing the first two column stops 21 and 22 to pass over it "and when the parts are in the fourth position, in Whichthe denominational stops are shown in Fig. 4, said denominational stops are only high enough to arrest the fourth column stop 24 and not the others.

It will be perceived that this device can be used as a simple column selector by always operating the denominationalkey of lowest order for example, and that by operating any `selected denominational key the carriage can be brought at a single operation to any selected denominational position in any selected one of the four columns; It will 'also be perceived that in case most of the tabulating work has its beginning in a certain one of the columns, say,` in the third, then the handle 6l can be set in its third position land the keys 40 be operatedatter the ordinary manner of a denominational tabulator which will bring all of the tabulated work into the same column. If there is some unusual item that requires to be tabulated in another column, the handle (3l can be moved accordingly. In short, when the machine is set lfor a certain column this setting is retained until it is changed by an operation of the handle 61.

It will be perceived that the selection of columns is effected by shifting the support to which the denominational -stops are pivoted; that'the entire series or gang of denominational stops are shifted bodily to ditl'ei'ent positions corresponding to the different column stops; that the points 31 at which the actuating links 30 are connected to the denominational stops, partake of this shifting movement; and that the links 30 are also shifted, swinging about their lower ends 32.

'It will be perceived that my tabulator is capable of quite a' wide range of work and that at the same time-it is simple in construction and efficient for all its purposes.

Various changes may be made in the details of construction and arrangement Without departing from my invention.
